* Commit new test output

* Fix to not panic when type is undefined

* Fix to not panic on use of the any type

* Update test and generated output

* Fix error message after rebase

* Add sim test for push type error

* Fix acription to more general array element type

* Fix to coerce point types

* Change array push to not error when item type differs

* Fix coercion tests

* Change to only flatten as a last resort and remove flattening tuples

* Contort code to appease doc generation

* Update docs
